My local Lotus dealer is a resller for KT and few other options. They've done several tunes to different levels. You may want give them a call pick their brain.Shame, don’t seem like anyone here in the US sees the market in these cars.
Lotus doesn’t want the aftermarket support on these cars. Which sucks because the platform has potential.
All the good stuff is getting done by Jubu and Komotec, but unfortunately their customer service isn’t as good as Gregs at GRP here in the states.
Keep us posted on how things go with you. Interested in the sound change.
